【 摘 要 】

References(64)Avian influenza A, a highly pathogenic avian influenza, is a lethal infection in certainspecies of wild birds, including some endangered species. Raptors are susceptible to avianinfluenza, and spatial risk assessment of such species may be valuable for conservationplanning. We used the maximum entropy approach to generate potential distribution modelsof three raptor species from presence-only data for the mountain hawk-eagleNisaetus nipalensis, northern goshawk Accipitergentilis and peregrine falcon Falco peregrinus, surveyedduring the winter from 1996 to 2001. These potential distribution maps for raptors weresuperimposed on avian influenza A risk maps of Japan, created from data on incidence ofthe virus in wild birds throughout Japan from October 2010 to March 2011. The avianinfluenza A risk map for the mountain hawk-eagle showed that most regions of Japan had alow risk for avian influenza A. In contrast, the maps for the northern goshawk andperegrine falcon showed that their high-risk areas were distributed on the plains alongthe Sea of Japan and Pacific coast. We recommend enhanced surveillance for each raptorspecies in high-risk areas and immediate establishment of inspection systems. At the sametime, ecological risk assessments that determine factors, such as the composition of preyspecies, and differential sensitivity of avian influenza A virus between bird speciesshould provide multifaceted insights into the total risk assessment of endangeredspecies.
